UAH computer engineering doctoral student Vahid Heydari's poster on "Preventing Remote Cyber Attacks against Aircraft Avionics Systems" was recently named
the best poster at the 11th International Conference on Cyber Warfare and Security in Boston.

"Receiving the best poster award means we are exactly on the right track and have a lot of work to do on this topic," says Heydari, who also presented a
paper on his research at the conference.

His research exploits the abundance of addresses available in the new Internet Protocol version 6 (IPv6) to change a networked device's IP address
repeatedly at a very fast pace. The concept, called moving target defense, moves an IP address around rapidly to avoid it being found by an attacker.

I am working on a Moving Target Mobile IPv6 Defense (MTM6D) that changes the IP addresses randomly and dynamically to prevent remote attacks in the reconnaissance step.

"IP connectivity is increasingly used in aircraft systems, creating the possibility that unauthorized individuals might access and compromise aircraft
avionics systems," says Heydari. "I am working on a Moving Target Mobile IPv6 Defense (MTM6D) that changes the IP addresses randomly and dynamically to
prevent remote attacks in the reconnaissance step. Because it uses dynamic IP addresses, it will be very hard for attackers to target a system."

"Fortunately, I found a lot of interest in this topic in the conference," Heydari says. "According to the feedback, this method can increase the security
of aircraft and prevent cyber-attacks. Adding this method to aircraft avionics systems can open an avenue for the uninterruptible autopilot system to
prevent events like the 9/11 attacks, Malaysia Airlines Flight 370 crash or the Germanwings Flight 9525 crash."

Heydari attended seven presentations that focused on moving target defenses. "I talked with all of them and obtained some valuable comments for my future
work."

"His research proposes a possibility to prevent remote cyber-attacks against undisclosed computer application vulnerabilities, while current technology -
such as firewalls or intrusion detection systems - can prevent the attacks only against known vulnerability exploits," says Dr. Seong-Moo (Sam) Yoo,
associate professor of electrical and computer engineering and Heydari's advisor. "His research could be applied to protect national critical
infrastructure networks."

Many researchers and government agencies are interested in moving target defense, says Dr. Tommy Morris, director of UAH's Center for Cybersecurity
Research and Education.

"Vahid has found a way to use standardized IP version 6 protocol techniques to achieve an effective moving target defense," Dr. Morris says. "Vahid's
poster was about using moving target defense to defend an avionics system - that is just one of many applicable areas. Moving target defense is useful for
industrial control systems, personal computers, servers, the Internet of things and in many other domains."

Heydari says the cybersecurity field is broad and there's room for a lot more innovative research by UAH students.

"Cyber-attacks are the biggest threats for new technologies and we have expert faculty in this field who can advise students," he says. "Some of them that
I am happy to know are Dr. Seong-Moo Yoo, Dr. Tommy Morris and Dr. Sun-il Kim."
